Laurie,
I need to issue a buffer authorization for this, I can either do it as a mod to permit #10-0347 or as a new authorization.
They need it asap since they are having trouble and are already under construction. I told them since it was a buffer
auth. Only it wouldn't need an app. fee (so I'm not sure how to do it as a mod to the existing permit as that would
require a fee right?) and since I have all the info I need in the current file, I told them these documents were sufficient
for me to issue an approval. I've went to the site last week.
How do we handle this in BIMS and what DWQ# should I use? Thanks.

Sue & Shannon,
Please find attached the No Practical Alternative request for the temporary' bypass for the Lift Station at GTCC.
Also, find enclosed the proposed plan showing the culvert and the disturbance and the Reforestation plan. As discussed,
we are proposing a temporary culvert with filter fabric below the outlet of the culvert down to the stream banks and into the
stream. We are informing the contractor that the filter fabric needs to be stapled to the banks to keep it in place and will
make sure that it gets done right.
With our proposed approach we don't foresee much stream bank disturbance but we wanted to make sure that the pipe is
sloped gently to avoid high velocities/erosion at the pipe outlet. The pipe will be installed using a mini-track-hoe. I hope I
didn't miss anything here from our previous discussions but please let me know if I did and I will make changes
accordingly.
Please let me know if you have any questions or'comments or if you need additional information.

think that an 18", at 1 % would work.. if you do a 15" it would have to be at 2.4% which I am a little concerned with the

I talked to Shannon. He wants y6u'to install a pipe but have the outlet at the same
location as the-current pipe just at a lower elevation. He said the black fabric can stay in
place but suggested using longer staples to keep it in place. He basically said you only
have to lower the elevation enough to get it so that the pipe will have some "fall" and
was in agr ent with me that ygq shogl;dn t need-to disturb the actual stream bank.

That way we hope that the roots underneath the black fabric will hold the bank together
and allow faster restoration once the temporary pipe is removed.

Good morning-Sue
We have been talking to DLR & Shannon and here is the latest advice he gave us... he
hasn't been a big fan of the swale from the beginning and after the site visit he would
prefer for..,, install a temporary ggylver ps a .first option. The approach to me sounds
good froneering perspective but7wanted`fo ask you from a Jordan buffer
perspective
I've allowed ypass culverts'in the'buffer,(bypass from level spreaders vs having swales)
when the slope is too steep or in other extreme circumstances that we feel a swale would
do more harm than good. How do;you feel about what Shannon is suggesting we do? We
are going with-the assumption that everything is temporary and will be removed,
reforested and brought back to original grade after construction is done.
Please let me know, If this sounds like an acceptable measure that you could consider I
Will do the letter based on Shannon's proposed solution. I will have to get the engineer to
change the cawing and send you?,?the letter for no I&actical alternative and reforestation
plan
Thank you a and I hope you haV'e a great Weekend.

y 't,

Virginia,
After visiting the site today, I would recommend that you install a temporary
culvert f e ditch line to the stream. Cyrrejitly, the contractor is using a 15"
pvc culve a.conveythe.water4o the streaii via a mechanical pump. It looks
like the'ditch line is "I81'?,Ii wer than the-stream banks; If you use a temporary
culvert, you can provide inlet protection at the inlet to capture any sediment from
the roadway before it flows through the culvert and into the stream. We could
place the filter fabric below the outlet of the culvert down the stream banks and
into the stream, like what is in the field now. The fabric would need to be stapled
to the banks very good to keep it in place. This will allow very minimal stream
bank disturbance (just enough to install the culvert and obtain positive drainage).
I would thix?tk tfie:filter fabric will protect-the. banks instead. of installing rip-rap.
By installing a temporary eulvert'(and using a mini-track hoe for installation), I
believe this would be the less intrusive method to divert the water around the
pump station area. I guess the 'question would be: will DWQ allow a temporary
culvert piped directly into the stream in the buffer?
I-would estimate that the elevatiop from the bottom of the stream to the top of the
stream b ould be -4-5', very close to whit the topo shows on the plans. If
you can't?temporaryy.cufvert and have..to install.the'., swale, you will need to
obtain a ve ' "gradual slope on'the channel to keep it from washing. The diversion
would need to outlet on the same ``grade'as the stream bed. It could be slightly
higher if you wanted to stabilize 'the swale with rip-rap. The entire swale would
have to be seeded & covered with an adequate matting. A good rock check dam
would have to be installed at the outlet end of the swale to capture any sediment
prior to seed germination.
1 ? t
The. contra a'as constructed diversion"berm along Leabourne Rd, so any
water alon the roadway is'now 4irec?e into the culvert under the pump station
access road. This should help reduce the amount of water that was going toward
the pump station.
Let me know what you decide to do. I should be able to approve any change
using a pdf and email for documeptation since this is a minor change. Thanks.

Virginia,

I have looked over the pdf you sent. I do not see a problem with installing a
culvert across the access road. You will need outlet protection below the culvert
outlet. However, I do not think grading a diversion directly to the stream is a
good idea,J would recommend termipating the-diversion ditch at the edge of the
stream buffer .This would allow sheet flow info and across the buffer zone. If
you want t make some changes to the pdf `and resend them to me, that will be
fine. However, at the moment, I, do not think I could approve the changes as
shown. Thanks.

Shannon and Chuck,
I am trying to help with the process of getting approval for some temporary buffer
disturbance at the GTCC lift station site. They have had several stormwater issues onsite
and asked me if I could help them with the buffer part of the permitting. The main issue is
that when it rains hard there is a lot-of water draining into the site and it is making the
constructiori,of the lift station very difficult and has some people worried about what could
happen if we don't handle the.storm drainage soon. From what I hear with the severe
rains that w_e have had his fall-some of the water from the access road and upstream of
the access road was actually draining into the hole for the lift station and as you know
that it's a very expensive hole 0 (half a million $)...
The attached plan shows the temporary measures proposed for the work and since it
involves temporary buffer disturbance I contacted Sue Homewood for her advice and
approval. We also wanted to check with you and see if you are ok with the proposed
temporary measures. Do you have sometime in the.next couple of days to meet with us
onsite?
With more rain is coming .our way and sinceaccording to the predictions we may get
between 1-2 inches we met with Sue and Corey today. The contractor has installed
some temporary measures before we get our official temporary disturbance approval
(pipe on the surface that drains the water from the sediment area to the stream).
Sue and Corey suggested that we contact you to see if you need anything additional to
what is shown on the plan. Our main question is if you feel that an energy dissipator is
needed after the swale (right where„the temporary swale is discharging into the stream).
If one is needed I need to take that,(or any additional temporary measures that you may
need) into coreideration and include that information on the letter to Water Quality.
Please let me know if you have anytime in the`next couple of days. Tomorrow morning I
am pretty open but I have planning board in the afternoon. On Thursday I have a meeting
at 11 am and one at 3:30 and Friday is open.
Thank you so_much for your help and let me know about the meeting or if you want to
discuss over the phone instead. I also have some pictures that I can send you to better
illustrate what's going on onsite. Sorry for the short notice but your help is greatly
appreciated.

Re: 3930.20 - NW GTCC Northwest Campus Water and Sewer - Lift Station
Dear Ms. Homewood:
The City of Greensboro is submitting to a No Practical Alternative Request to the State of North Carolina's
State of North Carolina's Rule 15A NCAC 02B.0267 - Jordan Water Supply Nutrient Strategy: Protection of
Existing Riparian Buffers. The project location is south of Pleasant Ridge Road in Guilford County, North
Carolina. As shown in the attached plan, the temporary system to bypass the stormwater runoff for the site in
reference will entail a temporary disturbance of approximately 285 sf in Zone 2 of the Jordan Lake Stream
Buffers and approximately 320 sf in Zone 1 of the Jordan Lake Stream Buffers.
The Zone 1 & 2 disturbances are necessary to allow for the construction of a temporary stormwater bypass to
handle the runoff from the access road, required to avoid stormwater draining into the construction area for the
lift station. As shown on the plan, the proposed bypass system consists of an 18"culvert under the access road
to route the water from the west ditch to an 18" pipe to be installed within the buffer. The proposed 18" pipe at
1 % slope is needed to handle the runoff from both access road ditches. A rock pipe inlet protection is proposed
on the upstream area of the pipe and on the downstream area matting (Nagreen C350) should be installed. No
stream disturbance should take place as a result of this temporary fix.
Following the completion of construction, the temporary bypass system will be removed and the stream buffer
will be restored to its current state.
The City of Greensboro investigated other options to bypass the surface water and drain it away from the
construction site for the lift station. A swale was considered but it was suggested by the Division of Land
Resources that the proposed pipe would be a much desired temporary fix.
Please review the included information and feel free to call if you have questions or require additional
information at [phone]. We would also be glad to meet with you to review and discuss further as
necessary.

Reforestation Plan Temporary Buffer Disturbance GTCC Lift Station
Approximately 700 sf. of stream buffer will be temporarily disturbed to install a bypass system for
stormwater. NCDENR Stormwater BMP Manual provides guidelines for the reforestation of a Riparian
buffer. Trees should be planted approximately at a density sufficient to provide 320 trees per acre and
shrubs should be planted at a spacing to provide 1,200 shrubs per acre. Trees should be planted at a
spacing of 8x8 to 10x 10. Shrubs should be planted at a spacing of 3x3 to 5x5.
For approximately 650 sf of disturbance 5 trees will be needed.
For approximately 650 sf of disturbance 18 shrubs will be needed.
